Azure Service Bus Connector 3.0 Reference - Mule 4

Anypoint Connector for Azure Service Bus (Azure Service Bus Connector) enables message integration with Azure Service Bus on the cloud.

Configurations

Parameters

Name Type Description Default Value Required

String

Name for this configuration. Connectors reference the configuration with this name.

x

Connection

Send Correlation Strategy

Enumeration, one of:

  • AUTO

  • ALWAYS

  • NEVER

Whether to specify a correlation ID when publishing messages. This applies both for custom correlation IDs specified at the operation level and for default correlation IDs taken from the current event.

AUTO

Zone Id

String

Zone ID property is used to identify the rules used to convert between an Instant and LocalDateTime. If the Zone ID equals Z, UTC is used. If the Zone ID is not specified, the system default Zone ID is used.

Expiration Policy

Expiration Policy

Configures the minimum amount of time that a dynamic configuration instance can remain idle before Mule considers it eligible for expiration. This does not mean that the instance expires at the exact moment that it becomes eligible. Mule purges the instances as appropriate.

Connection Types

Shared Access Signature

The SAS connection type uses the SAS Key Name and the SAS Key to generate a token, which is used by the Azure Service Bus SDK to establish the connection to the Service Bus instance.

Parameters
